I need an iOS app that:
Uses WebView to load https://klikici.com with full functionality (JavaScript enabled).
Includes an update notification bar that appears only when a new version is available, fetched from a JSON file hosted on my server.
Supports back navigation in the WebView (go back or close the app).
Is compatible with iOS 12+ and meets App Store guidelines.

Deliverables:

Fully functional iOS app.
